I recently purchased a Electronic Load to test some small power supplies. I often use little power supplies for small LED or ESP8266 projects and since I mostly buy stuff in China I often don't really know how good those power supplies are. So I thought I would get a load bank and at least have the ability to test how they behave. I probably won't be doing any full teardowns of the power supplies (There is other people around who are A LOT better at that) but at least I can do some testing. I will also allow me to do some battery testing and other stuff I've been wanting to do. I made a video of a first look about the ZKETECH EBD-A20H below. This version has 0-30 voltage range with 0-10 Amperage range and 4 wire measurement.
For a while now I've been interested in several types of power adapters and power delivery. This started with LED drivers and 12v/24v power supplies for LED lighting. There will be more about that in later blog posts. For this firs time tryout talk video I'm talking about phone chargers, how they have changed over the past few years and my plans on testing them in follow up videos and blog posts! Let me know what you think and leave a like if you liked it on youtube!
A while back I tested a "dumb" active POE switch. But I still have devices which require passive POE and I don't want a mess of cables and injectors. So I took a closer look at passive PE and what is possible with it. For this I tested some devices and you can view my review below. --Sale: I have these injectors and switches for sale!

Routerboard / Mikrotik just released a new product called the hAP AC. It's the first product they have ever released featuring a 3x3 2.4Ghz and 3x3 5.0Ghz AC radio's, 5 Gigabit ports, Passive POE (11v-57v) in and out and a SFP + USB port! I thought it would be worthwhile to run some tests on it and to share it with everyone. --Sale: I have some hAP AC for sale! Contact me using quindor@gmail.com or IM for prices! Also take a look at my article about Passive Gigabit POE above!
Ever since I started tinkering with hardware I've been accumulating more and more "stuff". Most often these are little things like connectors, sensors, mosfets, etc.. And more often then not I don't buy 1 or 2 but buy them per 10 or even 20 at the same time.
After a while I was having trouble keeping it all sorted and easily accessible so I started to look around for a cost effective way of storing everything and I think I might have found it. Read on to see what I'm using.
